GALVANO-ELECTRIC TH ERAPEUTIC CHAIN.

SPECIFICATION forming part of Letters Patent N o. 700,7 83, dated May 27, 1902. Application tiled March 19, 1902. Serial No. 98,973. (No model.)

To @ZZ whom, it may concern:

Be it known that I, AUGUST KRGER,manu facturer, a subject of the King of Prussia, German Emperor, and a resident of 73 Oberwiek, Stettin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Galvano Electric Therapeutic Chains, of which the following is an exact specification.

My invention relates to a galvano-electric therapeutic chain by means of which a galvanic current is produced in case the chain is situated upon the human body, which current produces a -salutary effect upon the human organism, increases the general health and tone of the body, and even has the effect of removing nervous and similar ailments.

My invention is represented in the accompanying drawings, in which- Figure l shows the lower part of the chain provided with a dry element. Fig. 2 is a side View of a single link of the chain.

The chain consists of links each of which forms a galvanic dry element, which links are connected to each other by means of metallic rings. Each link consists of a copper cup a, which in order to prevent the oxidation of the same is gilded, and of a zinc cup b. Between both 4cups a material c, adapted to absorb the moisture arriving from the pers piration from the body of the wearer or the moisture of the atmospheric air, is situated. Advantageously a wick, a piece of flannel, or the like is used for this purpose. Both cups are kept together by means of a string d, situated in grooves provided in the cups c and b, as may be seen from Fig. 2 of the drawings.

As soon as the material c becomes damp the copper and zinc cups, in connection with the material situated between the same,which has become conductive by the moisture,forms a galvanic element. On the metal cups aand. b projections c are provided on both sides, which projections are provided with holes j', in which rings g are situated. These rings serve for connecting the single links or elements and are arranged that way that always the like poles of the elements are connected to each other.

In this chain the dry element h is inserted in that way that the -ipole of the element h is connected to thev -ipole of the link elements, while the pole of the dry element h is connected with the pole of the link elements. The electrical connection between the poles of the elements hand the poles of the chain -links' is effected by means of small chains t', while the whole element is connected to the chain by means of non conducting strings k. The connection of the dry element with the chain is advantageously such as to enable people to easily insert another dry element with stronger or weaker current.

I am aware that galvanic chains consisting of cups of copper and zinc separated by a material adapted to absorb the liquid arising from the perspiration from the body are known That is why I do not claim this idea broadly; but

What I claim as my invention, and desire to secure by Letters Patent of the United States, is-

In a galvano-electric therapeutic chain, the combination of a plurality of chain-links, each consisting of a copper and a zinc cup separated by a moisture-absorbing material, the like poles of the galvanic elements, formed by the links, being connected to each other, with a galvanic dry battery inserted between two adjacent links of the chain, the poles of which battery are connected to the like poles of the chain, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses. y Y

AUGUST KRUGEE.
